Design of a Bilayer Metalens for Red, Green, and Blue‐Achromatic Imaging with Wide Field of View
Advanced Photonics Research, Volume 6, Issue 11, November 2025.Herein, an RGB‐achromatic bilayer metalens with a wide 80‐degree field‐of‐view and a high 0.65 numerical aperture is presented. Using silicon nitride meta‐atoms, it maintains consistent focal lengths for red, green, and blue light, even at oblique angles.

General Calibration Algorithm for Single-transmitting-dual-receiving Polarimetric SAR System
Leida xuebao, 2012 The single-transmitting-dual-receiving polarimetric SAR system has only two receving channels, which induces lack of prior information for calibration. Due to the polarization diversity of this kind of system (which operates on different dual and compact

Polarization‐Improved Bidirectional‐Pump Atomic Magnetometer Based on Spin‐Decoupled Metasurface
Advanced Science, Volume 12, Issue 37, October 6, 2025.The polarization‐improved bidirectional‐pump atomic magnetometer based on spin‐decoupled metasurface has been experimentally demonstrated. The system, based on a metasurface, successfully realizes precise control of atomic spin polarization. The research not only offers a novel technique for designing high‐performance optically pumped atomic ...
